Beyond the harvest
Buckwheat as a hunting food plot.
Buckwheat is a top dove-hunting cover crop — flowers attract pollinators all summer, then seed-out in late summer brings doves to the field. Time planting 70-80 days before opening day of dove season.
Buckwheat and your farm pond.
Buckwheat flowers attract pollinators which support insect populations that feed bass fingerlings and bluegill in your farm pond.
